Schenck's knee dislocation (KD) I injury: An uncommon pattern

Area of Science:

• Orthopedic Surgery
• Knee Ligament Injuries
• Diagnostic Imaging

Background:

• Schenck's knee dislocation (KD) I is a rare injury pattern characterized by a knee dislocation with at least one central pivot ligament intact.
• Accurate classification of knee dislocations is crucial for effective treatment and patient outcomes.
• Distinguishing true KD I from other multiligament knee injuries is essential to avoid misclassification.

Observation:

• This report details a case of knee dislocation in an 18-year-old patient.
• The patient presented with a specific pattern of knee dislocation.
• Diagnostic imaging and physical examination were critical in identifying the injury characteristics.

Findings:

• The presented case involves a knee dislocation with a preserved posterior cruciate ligament, fitting the definition of Schenck's KD I.
• The study highlights the importance of correlating imaging findings with clinical examination for accurate diagnosis.
• The authors caution against overreporting of Schenck's KD I due to misclassification of other severe knee injuries.

Implications:

• Correctly identifying Schenck's KD I ensures appropriate surgical planning and management strategies.
• Improved diagnostic criteria can lead to better patient outcomes and reduced long-term complications.
• This case underscores the need for precise classification of multiligament knee injuries in clinical practice and research.
